围手术期化疗加外科手术治疗晚期胃癌

Objective To investigate the feasibility and safety of designed perioperative surgical treatment for advanced gastric cancer.Method From March 2006 to Sep.2009,24 patients with advanced gastric cancer were enrolled for this study,of which 14 cases were graded as Ⅳ M0,10 as Ⅳ M1,including liver metastasis in 5 cases,peritoneal seeding in 4 and lung metastasis in 1.All patients received 2-4 cycles of chemotherapy of PCF or ECF regimen,followed by intended surgical resection and postoperative 2-3 cycles of adjuvant chemotherapy of the same regimen as used during the preoperative course.Result Seven Cases abandoned surgical therapy,a total of 17 cases completed preoperative chemotherapy,surgical resection and postoperative chemotherapy.R0 resection was achieved in 16 cases(94%).There was no perioperative mortality,and total clinical response rate was 75%,overall pathological response rate was 82%.In 59% surgical cases (10 cases) serum CEA and CA199 has returned to normal;In 71%patients tumor pathological stage degraded at the cost of Ⅲ-Ⅳ grade of neutropenia,thrombocytopenia,anemia,severe nausea and vomiting in 79%,8%,13%,and 54% cases respectively.Fever was encountered in 2 cases with grade Ⅲ-Ⅳ neutropenia.Conclusion Designed perioperative chemotherapy regimen renders advanced gastric carcinoma patients operable at the cost of acceptable complications.     

Phase Ⅱ study of docetaxel,cisplatin and capecitabine as preoperative chemotherapy in resectable gastric cancer

AIM To investigate the feasibility of preoperative docetaxel,cisplatin and capecitabine(DCC) in patients with resectable gastric cancer.METHODS Patients with resectable gastric cancer fulfilling the inclusion criteria,were treated with 4 cycles of docetaxel(60 mg/m2),cisplatin(60 mg/m2) and capecitabine(1.875 mg/m2 orally on day 1-14,two daily doses) repeated every three weeks,followed by surgery.Primary end point was the feasibility and toxicity/safety profile of DCC,secondary endpoints were pathological complete resection rate and pathological complete response(p CR) rate.RESULTS All of the patients(51) were assessable for the feasibility and safety of the regimen.The entire preoperative regimen was completed by 68.6% of the patients.Grade Ⅲ/Ⅳ febrile neutropenia occurred in 10% of all courses.Three patients died due to treatment related toxicity(5.9%),one of them(also) because of refusing further treatment for toxicity.Of the 45 patients who were evaluable for secondary endpoints,four developed metastatic disease and 76.5% received a curative resection.In 3 patients a p CR was seen(5.9%),two patients underwent a R1 resection(3.9%).CONCLUSION Four courses of DCC as a preoperative regimen for patients with primarily resectable gastric cancer is highly demanding.The high occurrence of febrile neutropenia is of concern.To decrease the occurrence of febrile neutropenia the prophylactic use of granulocyte colonystimulating factor(G-CSF) should be explored.A curative resection rate of 76.5% is acceptable.The use of DCC without G-CSF support as preoperative regimen in resectable gastric cancer is debatable.

Pancreatic adenocarcinoma: Outstanding problems

Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive malignant tumors with an overall 5-year survival rate of less than 4%.Surgical resection remains the only potentially curative treatment but is only possible for 15%-20% of patients with pancreatic adenocarcinoma.About 40% of patients have locally advanced nonresectable disease.In the past,determination of pancreatic cancer resectability was made at surgical exploration.The development of modern imaging techniques has allowed preoperative staging of patients.Institutions disagree about the criteria used to classify patients.Vascular invasion in pancreatic cancers plays a very important role in determining treatment and prognosis.There is no evidence-based consensus on the optimal preoperative imaging assessment of patients with suspected pancreatic cancer and a unified definition ofborderline resectable pancreatic cancer is also lacking.Thus,there is much room for improvement in all aspects of treatment for pancreatic cancer.Multi-detector computed tomography has been widely accepted as the imaging technique of choice for diagnosing and staging pancreatic cancer.With improved surgical techniques and advanced perioperative management,vascular resection and reconstruction are performed more frequently;patients thought once to be unresectable are undergoing radical surgery.However,when attempting heroic surgery,a realistic approach concerning the patient’s age and health status,probability of recovery after surgery,perioperative morbidity and mortality and life quality after tumor resection is necessary.

骨盆骨肉瘤的外科治疗策略探讨

Objectives To investigate the clinical outcome of consecutive pelvic osteosarcoma treated with surgery and chemotherapy in a single institution, and to discuss the surgical strategy, resection and reconstruction. Methods Twenty-one consecutive cases with pelvic osteosarcoma underwent surgical procedures between June 2000 and June 2009. There were 12 male and 9 female with a mean age of 32 years. According to Enneking and Dunham pelvic classification system, type I was 3 cases, type I + IV 3 cases,type I + Ⅱ 4 cases,type Ⅱ + Ⅲ 4 cases,type I + Ⅱ + Ⅲ 1 case,type Ⅲ 1 case,and type I + Ⅱ + Ⅳ 5 cases. Among the 21 cases, 19 were diagnosed as classical osteosarcoma and 2 were diagnosed as low-grade pathologically. All the tumors were stage Ⅱ B. All the patients received en-bloc resection with 13 wide resection and 8 marginal resection. Thirteen patients underwent modular hemipelvic endoprosthesis reconstruction, and 5 patients underwent rod-screw system reconstruction combined with autograft. Two patients received hemipelvectomy and one type Ⅲ patients had resection without reconstruction. The mean follow-up period was 30. 3 months (range,6. 0-87. 0). Results Thirteen patients out of 21 survived after treatment The overall survival rate was 61. 9% , and 23. 8% patients were alive without disease. The estimated 5-year survival rate was 44. 2% based on Kaplan-Meier curve. The local recurrence rate was 28.6% , among which 4 cases were type Ⅱ resection, 1 was type I resection, 1 was type I + Ⅳ resection. No local relapse was found on the hemipelvectomy and type Ⅲ resection cases. The local recurrence rate after wide resection was 23. 1% ,and 37. 5% for marginal resection. Nine patients had lung metastases and one patient was found bone and lymph node metastases. The MSTS 93 function score was 20. 6±5. 4 for 13 patients,and 22. 5±2. 1 for rod-screw reconstruction cases. The function score was 17. 7±5. 5 for hemipelvic prosthetic reconstruction. Conclusion Limb salvage procedures could be performed on most pelvic osteosarcoma cases, and satisfying function outcome could be achieved with proper reconstruction,however,the overall survival is still lower compared with those in extremities.

140例胃间质瘤的外科治疗分析

Objective To analyze the outcome of the patients with gastric gastrointestinal stromal tumor (GIST) after surgical treatment and identify the associated risk factors. Methods Clinical data and the tissue slices including immunohistochemistry staining of 140 patients with gastric GIST from January 1990 to December 2008 were retrospectively reviewed. SPSS 16.0 for Windows software package was used for statistical analysis. Results The overall survival rates of 1-, 3-, 5-year were 96.8%,86.7% and 79.3%, respectively. The survival rates of 1-, 3-, 5-year were 98.1%, 90.0% and 85.4% in patients who underwent complete tumor resection. But the survival rates of 1-, 3-, 5-year were 38.1%, 0 and 0 in patients with incomplete tumor resection. The differences were statistically significant (P＜0.05). Gender, preoperative metastasis, tumor size, pathology type, karyokinesis, recurrence and metastasis were associated with survival rates in patients with complete tumor resection by univariate analysis. However, only tumor size, karyokinesis, recurrence and metastasis were associated with survival rates by Cox regression multivariable analysis (P＜0.05). Conclusion Surgery remains the main treatment for gastric GIST. Local complete resection is the principal treatment.
